# Create a lofted section between a rectangle and a circular section.
# 1. Establishes a workplane that an object can be built on.
# 1a. Uses the named plane orientation "front" to define the workplane, meaning
# that the positive Z direction is "up", and the negative Z direction
# is "down".
# 2. Creates a plain box to base future geometry on with the box() function.
# 3. Selects the top-most Z face of the box.
# 4. Draws a 2D circle at the center of the the top-most face of the box.
# 5. Creates a workplane 3 mm above the face the circle was drawn on.
# 6. Draws a 2D circle on the new, offset workplane.
# 7. Creates a loft between the circle and the rectangle.
